Oracle Database Administration 2019 Certified Professional — Question 21

Which three statements are true regarding ASM on a four-node cluster? (Choose three.)

Answer options

• A. ASM Cluster File System (ACFS) can be deployed on any nodes.
• B. A database instance on a node can be a client of an ASM instance running on any node.
• C. A database instance on a node cannot be a client of an ASM instance running on other nodes.
• D. A database instance on a node can only be a client of an ASM instance running on the same node.
• E. A database instance on a node uses an ASM instance as an I/O server when requesting I/O to diskgoups.
• F. An ASM instance and database instances can coexist on the same node.

Correct answer: A, B, F

Explanation

The correct answers are A, B, and F because ACFS can indeed be deployed on any node, and a database instance can access an ASM instance on a different node. Option C and D are incorrect as they contradict the functionality of ASM, which allows instances to communicate across nodes. Option E is misleading since it implies a limitation that does not exist; database instances do use ASM for I/O operations but can do so across nodes.
